Claims.

This invention relates to an automatic deodorizing device for use with volatile deodorizing solutions of the chlorophyll type, and has for its principal object the provision of an automatic device for use in rest rooms and other enclosed spaces, which will automatically expose the volatile deodorant to the air of the room when the door of the room is closed, and which will automatically seal the deodorant against evaporation when the door is open.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eiiiciency. These will become more apparent from the following description.

In the following detailed description of the invention, referenceis had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawings:

Fig. 1 is a side view of the improved automatic deodorizer illustrating it partially in section in the closed position and attached to a door casing;

Fig. 2 is a similar side view, illustrating the deodorizer in the open position;

Fig. 3 is a plan view thereof;

Fig. 4 is a side view, illustrating the opposite side of the deodorizer in the closed position; and

Fig. 5 is a cross-section, taken on the line 5-5, Fig. 4.-

In the drawing the tcp of a typical door is indicated at I0, with its upper casing .at II. The invention is designed to be yattached to the casing II by means of suitable attachment screws I2, or other attachment devices.

The improved deodorizer employs a supporting bracket I3 having an attachment flange I4 for receiving the screws I2. The outer extremity of the bracket member I3 is formed with a supporting cap I5 having internal threads for receiving a solution container I6 containing a volatile deodorant solution 33. The cap I5 is provided with a central opening which forms the outlet for the container I6.

The opening I'I is closed by means of a lid provided with a suitable sealing gasket I9. A hinge arm 20 extends from the lid I8 and is hingedly mounted on a hinge Din 2| extending horizontally through the bracket member I3. The opening movement of the lid is limited by means of a tail stop 25 projecting from the hinge arm 20 and positioned to contact a floor 26 in the bracket member I3.

One extremity of thehinge pin 2| is provided with a crank arm 22, from which a tension spring 23 extends to a pivot pin 24. The pivot pin 24 lis placed directly below the hinge pin 2|, and

the crank arm 22is inclined so that, when the vlid I8 is in the closed position, the tension of lthe spring 23 will pull the lid toward the cap I5 to bring the gasket t9 into sealing engagement therewith. Similarly, when `the lid is in the open position, the spring 23 will be swung ,to the opposite` side of the axis ofV the hinge pin 2| to pull the lid to its extreme open position.

The spring arm 422 is swung to either side of ythe dead center position by'means of a'swinging arm 2l mounted on the extremity of the pivot pinl 2 4. 'Ihe lower extremity of the swinging arm preferably carries aresilient roller 28. The upper extremity of the arm is turned outwardly, as shown at 29, to actuate a V-shaped lever 3U.

The V-shaped lever is secured on the hinge pin 2|, and its prongs overlie the outwardly turned extremity 29 of the lever 21.

The lid I8 is provided with any suitable attachment means, such as a perforated lug 3|, by means of which an absorbent wick 32 of fabric, cords or similar material is supported in the container I6. f

Let us assume that the door is closed and that the device is in the open position of Fig. 2. As the door I9 is swung open, as indicated by the arrow A in Fig. 1, the upper edge thereof strikes the roller 28 and swings the swinging arm 2l to the broken line position of Fig. 1. The yupper extremity of the swinging arm contacts the inner prong of the lever 25 and snaps the lever 22 past dead center so that the spring 23 will clamp the lid on the cap I5. 1

Now let us assume that the door is swung to the closed position, as indicated by the arrow B in Fig. 2. This causes the swinging arm 21 to move to the broken line position of Fig. 2 swinging the V-shaped lever to the solid line position of Fig. 2 so that the spring 23 will hold the lid in the open position. In the open position the absorbent wick 32 is exposed to the atmosphere of the room for the evaporation of the deodorant solution 33.

While a specic form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
